I wish your poll had differentiated Bitcoin Core and bitcoind.
Why separate two things that are the same? bitcoin-qt/bitcoind was renamed to Bitcoin Core a couple of releases ago.
That would depend on the context of the discussion. Some people might think that bitcoin-qt sucks and avoid Bitcoin Core altogether, unaware that they can use the bitcoind part independently with some other advanced client implementation built on top of it.
However, since we are talking about nodes there is probably no need to differentiate.
